I thought I would post this thread here as the forums often gets question from members and those looking to buy a GTO, Lemans, or Tempest. The question that comes up is "What should I look for.
Got some great pics of what to look for using my '68 Lemans as the example. It is a "southern" car, but don't be fooled into thinking it doesn't have rust or is better than a "northern" car as some of the typically sore areas that do rot don't care what part of the country you live in.
I knew I had rot at the windshield as it was self evident on my car because you could see it at the dash panel where it sets under the base of the glass. I also had water leaks at the top of the windshield that I simply cured by filling with silicone so I could drive it the years that I did. So no surprise and not anything for me that scares me.......just more sheet metal & fabrication work to do. Not doing a concourse restoration, so not looking for perfection, just a nice quality repair that will pass by most standards.
I had to remove the metal dash which was easy enough because it was all eaten away at the windshield. Not only am I going to have to fix the windshield channel, I will be adding metal to the dash panel to get it to lay back in the windshield channel as it should. Windshield posts are pretty bad as well.
What seems to be the main culprit? The old sticky seal that holds the windshield on and keeps water out was all dried up like a rock and had cracks, splits, and gaps all throughout. This allowed water to easily find its way to the underlying steel with the results being all the rot over the years. My windshield was not stuck into place as it should have been and I simply lifted it out without effort. Usually a windshield with a good seal needs to be "cut out" with the correct tools.
Dirt of course is known to collect under the windshield moldings and hold in moisture and rot away the windshield channels. So if the car is original, your windshield seal may also be gone and letting water get under it and rot away your windshield channels -while you don't even know it. Might be worth having yours replaced by a local windshield installer. If you find any rot, you can address it at that time and then re-install a new seal with your windshield.
Anyway, enjoy the pics. I will at some point post the repairs I will have done in the "Complete Exterior Body" thread once I have it all together and looking good again. This is goin' to take a few weekends of my time for sure.
